-To all whom if nutty eoneern:

the tiring of kilns, or in any other manner in \rhieh oil is burned to generate heat.

For the purpose of illustrating my iniproved proeess I show herein an apparatus in whit-h said proeess is used for the. manufacture of eo'nihustihle gas.

in the aeeonipairving drawings, Figure 1 is a broken side elevation of the apparatus.

Fig. 2 is a plan view thereof.

Referring to the drawings, 1 represents a easing lined with refractory n'iaterial 2 and forming a ehaniher, in the lower portion of \rhiels are arranged arches 3, on which are supported loosel \"piled hrielcs 4, said arches and l I'l l-CH being of refrzuitory material. Air admitted to the lHlliOllI of said ehamherliy an air-pipe 5, eontrolled liy a valve 5, and the produets ol' eonihustion pass out by an outlet 7, eontrolled by a valve 8, and thus into a staelq (l.

it, is a pipe diseharging into the air-inlet and thenee into the bottom of the ehainhei, said pipe ha ring two hrauehes l l 12, ofwhieh the hraneh H is used to admit oil and the i raneh lid to admit a eonipressed gas used for earrying out my improved process. 13 is an outlet for the nianul'artured gas.

The proeess is as follows: The air-inlet 5, the oil lipe H, and the valve 8 being open, oil is aif'niitted to the bottom of the ehaniher and is there burned, the products ol' eoinhus- Specification of Letters Patent,

rial and being converted into fixed gas. When the temperature of the refractory Inaterial has been sufficiently lowered by this stage of the proeess, the valves'fi and 8 are opened, and air is thus again admitted to carry out the heating stage of the process. This may be done Without closing the pipe 12.

The novelty of my invention consists in the eharaeter of the whieh is employed to spray the oil. ileretotore it has been eustoniary to use steam for the purpose; but this neeessitates the fornmtion of water-gas, Whieli ineertain cases is objeetionablc, and. moreover, the amount of steam admitted. is in exeess of that required for the inanufae ture of water-gas. Consequently the surplus steam'niust he eliminated hy means of scrubbers. Air has also been sometimes admitted for spraying the oil; hut this is very objeetionahle, as it eauses the resulting gas to he mingled with nitrogen ane. earhonic arid.

Now the esseneeof my invention consists in using instead of steam a gas whieh will not in'uriously atleet the gas produeed from the oil, as do hoth steam and air. The gas which is so admitted is preferahly a eon'ihustihle gas and will generally he that previously made by the same apparatus which is being used, a portion of the gas so made being cone pressed and returned to the apparatus and there utilized pray the oil. However, it is to he unden iod that any invention is not gas previously menu faetured in the selfsanie apparatus, out in eludes any whieh by its admixture with oil does not.- iniuriousl et the eaioriiie and lun'iinant properties thereof,

.lBy the. use of this apparatus boilers are rendered unnecessary, and. thus the moat meeting a gas plant is redneed, creating a wider held for the use of gas, and especially where. steam under high pressure is objectionable.

l The proeess of manufacturing gas which eonsists in heating refreetory material, then spraying oil by means of eompressed oomhustilile and passing it through the refractory material to make so long as the temperature of said material remains suiii eiently high, then admit-ting air to burn the oilljantl gas so admitted, and passing the pri'iducts of eoml, stion. through refractory material to reheat the same, then shutting off the. air and passing the oil, still sprayed the eoni'n'essed eonihustihle as throiwlx the l i r: 1-:

teriel to make gas therefrom, and repeat' the 0 eretion indefinitely, substantially as descri ed. H

In Witness whereof I have hereunto set my hand in the presence of two subseribing wit- I5 nesses.
